Title: Materials Data on LaB5O9 by Materials Project

Abstract

LaB5O9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.44–2.76 Å. There are five inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.37 Å) and two longer (1.38 Å) B–O bond length. In the second B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There is two shorter (1.46 Å) and two longer (1.50 Å) B–O bond length. In the third B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.46–1.50 Å. In the fourth B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.39 Å. In the fifth B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.39 Å) B–O bond length. There are nine inequivalent O2- sites. In themore » first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one La3+ and two B3+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one La3+ and two B3+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one La3+ and two B3+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one La3+ and two B3+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one La3+ and two B3+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one La3+ and two B3+ atoms. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one La3+ and two B3+ atoms. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent La3+ and one B3+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms.« less
